摘　　要：扭力轴是现代坦克最重要的弹性元件,其本身体积较小所处的工作环境也较为恶劣还要承受大量扰动载荷,坦克达到一定行程后扭力轴刚度会发生变化,针对坦克不同位置扭力轴承受不同扰动载荷,造成其刚度变化不同的问题;通过测量两种不同车型坦克的不同位置的扭力轴的刚度,探究坦克的不同位置的扭力轴的刚度变化规律;分析得出距离车体质心距离越小扭力轴刚度变化越小,安装减震器可以有效减少扭力轴刚度变化的结论。Torsion bar is the most important elastic element of modem tanks. The volume of torsion bar is small and its working environment is harsh. It also needs to bear the disturbance load repeatedly. There- fore, the stiffness of torsion bar will change when the tank reaches a certain mileage. The stiffness changes of torsion bars in different positions of the same tank are not identical because of the different load they take. Through the measurements of the stiffness of torsion bars in different positions on two models of tanks, we explored the rule of the torsion bar stiffness change in different positions of tanks. The conclu- sion is that the torsion bars closer to the vehicle centroid suffer smaller stiffness change, and the shock ab- sorber can help reducing the stiffness change effectively.
